Natural inoculum - Additional inoculations of races 15B and 151 at Fargo. Readings at soft dough to mid dough stages. 2 = Av. C.I. Average coefficient of infection. Percent severity multiplied by the following values for reaction types: VR & R = 0.2, is the average of the 5 coefficients of infection for each entry. Coefficient of infection M = Missing plants.
